04: The Forces
- #5A monkey is sitting on a tree limb. The limb exerts a normal force of 48 N and a frictional force of 20 N. Find the magnitude of the total force exerted by the limb on the monkey.Ans : Given: The limb of the tree exerts a normal force of 48 N and a frictional force of 20 N.

So, resultant magnitude of the force if given by
`` R=\sqrt{\left({48}^{2}+{20}^{2}\right)}``
`` =\sqrt{2304+400}``
`` =\sqrt{2704}=52\,\mathrm{\,N \,}``
∴ The magnitude of the total force exerted by the limb on the monkey is 52 N.
